Given a divisor A of a function field, there is a unique divisor of minimum degree that defines the same vector space of rational functions as A and there is a unique divisor of maximum degree that defines the same vector space of rational differentials as A. These divisors are called the floor and the ceiling of A. A method is given for finding both the floor and the ceiling of a divisor. The ...

This paper presents a localization of a mobile robot with two ceiling-view cameras in indoor environments. We propose the localization algorithm using the line feature and the corner feature between the ceiling and wall when a robot is in the local space. Also, we present the localization algorithm using the natural features such as bulbs, structures on the ceiling when a robot is in the large ...

The present study examined whether the compression of perceived visual space varies according to the type of environmental surface being viewed. To examine this issue, observers made exocentric distance judgments when viewing simulated 3D scenes. In 4 experiments, observers viewed ground and ceiling surfaces and performed either an L-shaped matching task (Experiments 1, 3, and 4) or a bisection...

We study resource synchronization in multiprocessor hard real-time systems. Speciically, we propose a multiprocessor resource control protocol which allows a job to simultaneously lock multiple global resources, removing a restriction from previous protocols. Allowing nested critical sections may permit a ner granularity of synchronization, increasing parallelism and throughput. All the protoco...

BACKGROUND In 2011, federal incentive payments for meaningful use of electronic health records (EHRs) began. This study evaluates the impact of the program on hospitals and EHR vendors, identifying how it affects EHR planning and development. Specifically, it assesses whether vendors and Chief Information Officers (CIOs) are viewing the meaningful use requirements as a floor - the minimally acc...

Simulations suggest residential cooling energy use can be reduced up to 15% through the use of ceiling fans with thermostat set-up. However, monitoring data from a large scale study of Florida homes found that air conditioning consumption was not lower because thermostats settings were not raised in response to fan use, and many fans were apparently left on for long periods in unoccupied zones....

The paper discusses acoustic problems in the contemporary Catholic church, and presents a study of influence ceiling structure on acoustics interior for two types structures, i.e. truss type reinforced concrete one. investigations involved six churches: three buildings with ceiling. results reveal that churches ceiling, parameters reach values close to recommendations. In contrast, create very ...

Three typical kinds of building materials (painted drywall, ceiling tile, and carpet) have been tested to study the effects of environmental conditions (temperature, relative humidity, and air velocity) on the sorption of volatile organic compounds (VOCs) by building materials. It was found that the effects of environmental conditions on sorption were insignificant for the painted drywall due t...

1887 quality of care but do not substantially reduce costs among a broad array of patients.3-5 As more empirical evidence comes in, it may become easier to identify specific ways to reduce costs; for now, the possibility and scope of the savings remain unclear. One approach that might improve the cost-effectiveness of disease-management and care-coordination strategies involves more accurately ...

BACKGROUND Eggcrate upper-room ultraviolet germicidal irradiation (UVGI), an engineering control method for reducing the airborne transmission of infectious diseases, was recently developed as an alternative to conventional upper-room UVGI using conventional louvered fixtures. A UV screen, which is composed of open-cell eggcrate panels supported in a frame designed for a conventional suspended ...
